AP Stats Teacher Advice (from a vet, not me)

As a part of my can't-believe-I'm-teaching-ap-stats preparations, I signed up for the electronic discussion group via the College Board's website. Following along with the discussion via my email inbox makes me feel oh-so 2002, but there have been a few helpful nuggets of advice, discussion, or desperation that have given me better perspective and preparedness.

Doug Tyson, of Central York High School in York, PA offered up this advice today on the EDG for me and my fellow first-years.

 Subject: Are you a new AP Stats teacher?

If no, then read no further.


If yes, I will break one of my long-standing rules in order
to write this message.  That rule is "Never offer un-asked-for
advice."  Although it has served me well over the years,
recent posts on this group have prompted me to offer 1 or 2
thoughts.  You are warned that these come from my very
own mind - read with eyes wide open...


1) Don't be afraid to admit to yourself, other AP teachers,
and your students that some of the material is subtle and
that you're still learning Statistics.


2) Real data are subtle and often break rules-of-thumb.  Be
wary of inviolate rules in Statistics, as they are often really
rules-of-thumb in disguise.


3) Think deeply about the ideas.  Get your students to do the
same.


4) Ask questions on this EDG. It's a safe place to learn.
There are lots of really knowledgable people here - I know
some of them, and they're really nice people.  And they
were all new Stats teachers at one point in their lives.


5) Read everything about Statistics you can get your hands on.


6) Develop a sense of wonder about the world around you.
Develop the same in your students.  Statistics (in one view)
is about understanding the world based on measurable evidence.
The world is your laboratory and playground.  Have fun!


Regards,
Doug

The EDG isn't as handy for me as Twitter, but I can't bring myself to unsubscribe.

Browser-based Interactive Whiteboard Software - Desmos

Have you ever...
  • Panicked because your interactive whiteboard's software stopped working?
  • Wished you could edit your whiteboard lessons from home without installing more software?
  • Wished you could share/email your whiteboard lesson to a parent or student with the same interactivity they would have with your file in class? (NOT a pdf, .doc, or ppt)
  • Wanted to embed your lesson content on your class blog or website?
  • Wanted an easy to use graphing calculator online?
Web start-up Desmos recently presented at TechCrunch Disrupt with a browser-based solution to interactive whiteboard software that is not dependent on any branded hardware OR software.  Our district uses SMART Notebook and can port those lessons at express.smarttech.com, which I've used this summer on the laptop I'm projecting from that doesn't have the software installed.  It's better than nothing, but its functionality is scaled down dramatically to basically opening files, inserting text, and drawing freehand.  You can't even insert images.

The software is still in alpha testing (as of the end of May), but I've applied for an account and hopefully will be able to play before the new school year starts.

Oh, BTW, I haven't even gotten to the graphing calculator that IS already live! (Which may end up being an even bigger deal; color-coded, cartesian and polar coordinates, zooming, sharing, integration with the whiteboard app)

Here's some video:

Open Source (everything)

I found an infographic via a Twitter follow about open-source textbooks from onlineschools.org. (Graphic to follow) The people at Flatworld Knowledge offer free e-books with extra options for self-print, black and white copies, and full color copies.  Much to the tune of any other open-source project, the info is reliable (if you generally believe in the reliability of open-source projects), and DRAMATICALLY cheaper.  I don't imagine that any of my EdTech books for my upcoming last semester will be available, but they've got several business titles, so anyone steering toward an MBA route is going to have more options.

I'm interested to see where these go.  (Only one math title to choose from for now.)
